6. Antennas and Cables Setting Up

6.1. Outdoor antenna installation

The repeater's main function is to improve weak RF signals in an area. The formula is: Input power +

Gain= Output power. The signal strength from an outdoor antenna directly affects the efficiency of the

indoor coverage. It is very important to choose the correct outdoor antenna location in order to get the

best signal.

If you don't know exactly where your operator's base station is located, go through the antenna aiming

process for getting the best result. To aim the antenna correctly, follow the steps below:

1. Setup the entire booster system, including antennas and cables, and power it on.

2. A person on the roof aims the antenna in a certain direction. The other person inside waits for 1

minute and checks signal level on the phone.

3. Then rotate the antenna its 1/8th of the way around, which equals 45 degrees. The person

inside does the same procedure with signal testing.

4. Repeat the process 8 times until you try all 8 directions, in every 45 degrees sector.

5. Compare the results of signal testing – the closer dB parameter to 0, the better booster

performance you get.

6. Fix the antenna in the direction with better signal result.

Note! We recommend mounting the antenna on the side of the building aiming away from the building,

which will reduce amount of possible obstacles. For your convenience and acceleration of the process

perform the testing in pair.

• The mobile phone shall display full bar signals in location where the outdoor antenna is installed

Phone calls or data transmission shall be smooth and stable. It is recommended to test the

signal 3 times in location where an outdoor antenna is to be installed

As shown from the illustration above, you should test the signals in points from A to E, and

select a best place that displays full bar signals.

• Outdoor antenna installation Requirements:

Outdoor antenna should be installed on the roof of the house or in some other place where your

mobile device is within coverage zone. Mobile signal should be as strong that at least three-four

bars are indicated on your phone display.

Outdoor antenna should be fixed in straightly.

It is necessary to waterproof connectors of the outdoor antenna and feeder lines.

Repeater is a two-way signal amplifier. So proper isolation between outdoor antenna and indoor

antenna is necessary in order to avoid self-oscillation. A perfect example of self-oscillation is

when you take a MIC and a loudspeaker for example; if they are too close to each other, it could

cause big noise.
